Contraves
Rheinmetall Air Defence AG is a division of German armament manufacturer Rheinmetall, created when the company's Oerlikon Contraves unit was renamed on 1 January 2009 and integrated with Rheinmetall's other air-defence products. Oerlikon Contraves was a Swiss anti-aircraft artillery manufacturer famous for its adaptation of the 1916 20 mm Becker as the Oerlikon 20 mm autocannon design, which was used in the Second World War and still in use today. Copies and derivatives of these designs were made by German, French, British and Japanese weapon manufacturers. Oerlikon Contraves was purchased by Rheinmetall in 1999. , Rheinmetall Air Defence had around 1,050 employees at locations in Switzerland, Germany, Italy and Canada. The group's sales were about . History Oerlikon's earliest predecessor was Schweizerische Werkzeugmaschinenfabrik Oerlikon, founded in the Oerlikon district of Zurich, Switzerland in 1906. In 1923 it acquired a factory in Germany. It entered the anti ...

RSA Missile
The RSA is one of the earliest surface-to-air missiles systems, developed by the Swiss companies Oerlikon-Bührle and Contraves starting in 1947. The missile went through a rapid development process with several upgraded versions, and was the first anti-aircraft missile offered for commercial sale when it was placed on the market in the RSC-50 form. The US tested 25 of the slightly different RSC-51 model under the name MX-1868. No further sales were forthcoming. Several improved versions followed, including the RSC-54, RSC-56, RSC-57 and RSC/ RSD-58. These saw small numbers of sales, mostly as training rounds. History Background Oerlikon had been a leader in the development of anti-aircraft weapons after its purchase of the SEMAG company in 1924, and the subsequent takeover by Emil Georg Bührle the next year. Their most famous products were the variety of Oerlikon 20 mm cannon that started at SEMAG and underwent considerable further development prior to the opening of World War ...

RSD 58
The RSD 58 is an early production surface-to-air missile system developed by Contraves-Oerlikon in Switzerland from 1947.David A. AndertonSwiss Build Mobile Anti-Aircraft Missile ''Aviation Week'', June 30, 1958. Test firings were made in Switzerland and Italy in 1958, and Japan placed a small order for training purposes, but the missile was not produced in high numbers. The missile system was developed from the earlier RSA Missile developed by the same companies. Design and development Contraves-Oerlikon started design work on guided missiles to supplement their anti-aircraft guns, like the popular 20 mm cannon, in 1947. The company produced a number of designs, including the RSA, culminating in the RSD 58 of 1958. The RSD 58 was a liquid-fuelled rocket-powered missile, guided to its target by riding a radar beam. The missile body was made of wrapped tubing and sheet with Araldite bonding while the wings were of sandwich construction. Targeting was by search radar and beam t ...

Rheinmetall Oerlikon Millennium Gun
The Rheinmetall Oerlikon Millennium Gun or Rheinmetall GDM-008 is a close-in weapon system designed by Rheinmetall Air Defence AG (formerly known as Oerlikon Contraves) for mounting on ships. It is based on the 35/1000 revolver gun land-based air defense system and uses Advanced Hit Efficiency And Destruction (AHEAD) ammunition. Description A device at the muzzle end of the barrel measures the exact speed of each round as it is fired, and automatically sets the fuse to detonate the round as it approaches a pre-set distance from the target. Each round disperses 152 small tungsten projectiles weighing each to form a lethal cone-shaped cloud to strike the incoming target. Whilst these are too small to do major damage in themselves, the accumulation of damage from multiple strikes is expected to destroy wings and control surfaces, sensors and aerodynamics, causing the target to crash. Other firing modes are designed to be effective against surface targets such as small fast attack ...

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on '' Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (' ...

Oerlikon (Zürich)
Oerlikon is a quarter in the northern part of the city of Zürich, Switzerland. A formerly independent municipality, Oerlikon was merged with Zürich in 1934 and forms today, together with Affoltern and Seebach, the city district 11. History The name Oerlikon goes back to the Alemannic settlement founder Orilo. Oerlikon was mentioned for the first time in the year 946 (other source: 942) as ''Orlinchowa''. At that time the town consisted of no more than one dozen houses. Later on it was part of the municipality of Schwamendingen, where the inhabitants of Oerlikon went to school and attended church. In 1855 the line from Oerlikon to Winterthur via Wallisellen was established by the '' Schweizerische Nordostbahn'' (NOB). The following year the line was extended to Zürich Hauptbahnhof through the Wipkingen Tunnel. Lines from Wallisellen to Uster (1856) and Oerlikon to Bülach via Glattbrugg (1865) followed. The opening of these lines triggered the industrialisation of Oer ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally " rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mo ...

Becker Type M2 20 Mm Cannon
The Becker Type M2 20 mm cannon was a German autocannon developed for aircraft use during World War I by '' Stahlwerke Becker''. It was first mass-produced in 1916 and was installed in a variety of aircraft. It was the only German autocannon to see service in the air during the war. The Becker also served as the pattern for the famous Swiss-built Oerlikon 20 mm cannon, which is in service to this day, and in a later form, was the original inspiration, through the Swiss design after World War I, for the World War II German Luftwaffe's MG FF (''Maschinengewehr Flügel Fest'', "fixed wing-mount automatic ordnance") 20 mm autocannon design. History Design and development The original design was based on the 19 mm Becker Cannon cartridge by the Conder brothers at ''Stahlwerke Becker'' of Reinickendorf, Germany. Development commenced in 1913 and was therefore already advanced when the War Ministry issued a specification in June 1915 calling for an aircraft cannon of u ...
